3.15 Pesticide counterfeiting, practice "fire eye golden eye", eight strokes to distinguish between true and false pesticides!

A large number of fake and low-quality pesticides will be found on March 15 every year, and fake pesticides cause great economic losses to farmers. I hope that the supervision departments of agricultural materials will vigorously supervise and do practical things for farmers. The most important thing is that farmers should practice their own "eye of fire" and buy real pesticides. We can distinguish the true and fake pesticides through the following aspects. I hope it will be helpful to you!

I. distinguishing between true and false product packaging

The label must be firmly affixed to the inner package of the pesticide preparation, or printed or marked directly on the package. The label includes, general product name, enterprise name, effective ingredient, dosage form, specification, pesticide registration certificate number, product standard code, quasi-production number, net weight or net volume, scope of application, method of use, application taboo, poisoning symptoms and first aid, drug damage, safety interval, storage requirements, etc. There should also be a category of pesticides at the bottom: herbicide-green; insecticide-red; fungicide-black; rodenticide-blue; plant growth regulator-dark yellow.

Second, three product certificates to distinguish between true and false

Domestic pesticides must be marked in the packaging pesticide registration certificate number, product standard certificate number, production license number (or approval license number), these "three certificates" are indispensable. On the other hand, the original imported pesticides are only marked with the pesticide registration certificate number and indicate the name of the country of origin in Chinese. Should carry on careful check when buying, all domestic pesticide "three card" mark is incomplete, not clear, it is fake medicine, do not buy.

1. Pesticide registration certificate: the temporary registration certificate starts with LS or WL. The official registration certificate number begins with PD, PDN or WP or WPN. The sub-packing registration certificate number is generally added to the pesticide registration certificate number provided by the original manufacturer with the abbreviation of "- mouth XXXX" representing the province (municipality directly under the Central Government), and XXXX indicates the serial number.

2. Production license number: HNPaaXXXX-b-yyyy where aa is the provincial and municipal code XXXX is the enterprise code, b is the product type, and yyyy is the product name.

3. Quality standard certificate: China's pesticide quality standards are divided into national standards, industry standards and enterprise standards, with certificate numbers starting with GB or Q respectively.

All the three certificate numbers that do not start with the above-mentioned LS, PD, XK, Q and other English letters are often written by producers or distributors themselves and are not protected by law, and their quality is questionable. We can report to the relevant departments in the process of purchase, and those who do not understand can also seek advice from others to prevent them from being deceived!

III. Distinguish between true and false registered trademarks

A registered trademark consists of two parts, one is the word "registered trademark", and the other is the trademark pattern, both of which are indispensable. on the label of imported pesticides, the "registered trademark" is replaced by the symbol "R". Counterfeit pesticides generally do not have the word "registered trademark" or pattern, even if there is a slight change. Some counterfeiters copy all the trademarks of other factories, but most of them do not write their own or real factory name on the label, or only write the name of the factory with an unknown address. In addition, in general, as long as the original label is not made by another factory, the imitation cannot be exactly the same. As long as it is compared with the original label, the flaw can be revealed.

IV. Distinguishing between true and false dosage forms of products

Because of its own characteristics, many pesticides can only be made into several fixed dosage forms, such as Bacillus thuringiensis products, only several dosage forms such as wettable powder, suspending agent, water dispersible granule and so on; proteins and oligosaccharides are mainly aquatic products. Before buying, look at the dosage form marked on the label.

1. Powder and wettable powder should be loose powder without agglomeration. If the color of the product is uneven, there are caking or there are more larger particles, can not be purchased.

two。 EC pesticides are generally light yellow or brown transparent liquid, no precipitation or suspended matter. If there is delamination, turbidity, precipitation, etc., there may be problems with product quality.

3. Suspensions and emulsions should be flowable suspensions without caking. Long-term storage, there may be a small amount of stratification phenomenon, after shaking should be able to restore the original state. Otherwise, there is something wrong with the quality.

4. If the fumigation tablet is in the form of powder, it indicates that it has failed.

5. The water agent should be a uniform liquid with no precipitation or suspended matter.

6. Granules should be uniform in thickness and should not contain more powder.

5. Distinguish between true and false product specifications

Biological pesticides such as plant sources, mineral sources, microorganisms, proteins and oligosaccharides are likely to be fake drugs with large usage, large packaging specifications and packaging specifications less than 50 ml (g). At present, the use of a bag of Bacillus thuringiensis in the market is 10 grams, and most of these pesticides are fake drugs. The amount of plant growth regulators (such as brassinolide, indoleacetic acid, etc.) and sex attractants is small, generally small packaging. Packaging specifications of more than 100 ml (g) are likely to be fake drugs. Biological pesticides such as plant sources, mineral sources, microorganisms, proteins and oligosaccharides are widely used, generally diluted less than 500 times. If the product indicates that the dosage per mu is dozens of milliliters (grams), or the dilution multiple is more than 1000 times, the product may be fake.

VI. Distinguish between true and false instructions for the use of products

The product description is the proper content on every pesticide label, and the content of the product introduction is consistent with the attributes of the drug, no exaggeration, clear text, smooth language, no wrong words and other characters. The content of the description shall include the characteristics, scope of application, appropriate dosage, method of use, time of use and matters needing attention of the drug. The introduction of counterfeit pesticides is often blurred in handwriting, arbitrarily exaggerating the role of the drug, and even wrong words and other characters, incomplete narrative content, poor sentence and so on, generally only from the phenomena of fuzzy handwriting and wrong words, typos, sick sentences, etc. it can be concluded that the drug is a fake pesticide or an unqualified pesticide.

The most common is that a product can be used in any crop, a formula can eat all crops, chlorine-sensitive crops use chlorine-high chlorine products, and random products increase production without a large number of demonstration tests. with an ammonium sulfate nitrogen fertilizer can be compared with urea, the package marked 21% nitrogen fertilizer + 46% of the total content of other medium and trace elements is called urea, and so on.

VII. distinguish between true and false in the scope of use of the product

There are many kinds of pesticides, and each pesticide has a certain control object and scope of use. Even for the same kind of pesticides, the scope of use and control objects of different varieties are also different. The utility model relates to a pesticide which can only control the nuclear polyhedrosis virus of cabbage armyworm. Some manufacturers label this pesticide to control pests such as cabbage armyworm, rice stem borer, rice stem borer and so on, which does not match the name and scope of application of the pesticide. Biological pesticides such as viruses and sex attractants generally work on only one kind of pest. If such pesticides are marked with multiple uses, the product may be fake.

VIII. Distinguish between true and false product prices

The price of pesticides is closely related to the effective components, content and product quality. If the price is significantly higher than that of similar pesticides, it is likely that other chemical pesticides have been illegally added; if the price is obviously lower than that of similar pesticides, they are likely to be cut corners and lack of active ingredients, which are fake and shoddy products, and do not buy such pesticides. Do not buy pesticides from mobile vendors who do not have a license because of greed, lest their rights and interests cannot be effectively protected after problems arise. To buy from a regular pesticide store with a complete license, and ask for a formal invoice, in case of problems in the future, you can recover the loss with the invoice.

Warm reminder: do not buy pesticide products in bulk. As the bulk pesticide adulteration is easy, the quality can not be guaranteed, after the problem, because consumers do not have the original packaging of the product, and it is difficult to determine and deal with it.

Pesticides can neither be eaten nor tasted, and their authenticity involves the vital interests of tens of thousands of farmers. Therefore, in the purchase of pesticides, do not be cheap, to carefully distinguish between real and fake pesticides.
